These neodymium magnets feature a rubber coating and are suitable for permanent outdoor or underwater use. The advantages of rubber coated magnets at a glance:
- Rust-resistant even in wet environments
- Protection against scratches on delicate surfaces, such as whiteboards and magnetic glass boards
- Substantially higher magnetic adhesive force in shear direction compared to neodymium magnets of similar size
Please note: The rubber coating may leave dark marks when the magnet is forcefully dragged over a surface. However, such marks can easily be removed with a moist cloth.
